In the most recent incident in the town, a car bomb and rocket attack on a traffic police station in Nusaybin killed two police officers and wounded around 35 people. No group has yet claimed responsibility for the attack, but it bears the hallmarks of the outlawed Kurdistan Workers' Party (PKK).

Earlier this week, residents in nearby Cizre returned to their homes to find most had been destroyed by shelling after authorities partially lifted a 24-hour curfew imposed to facilitate security operations against the PKK in the city. The Nusaybin bombing came a day after two female militants were shot dead after attacking a police station in Istanbul in a separate incident that underscored the volatile situation in Turkey.
